LOGGING TRAILER N Inventor alazuie E poTsey r/x Patented Apr. 22, 1947 UNITED STATES PATENT OFFICE LOGGING TRAILER Claims. 1

This invention relates to a novel construction of logging trailer and more particularly to an improved means for clamping a coupling pole to the trailer chassis.

More particularly, it is an object of this invention to provide a clamping means by which a wood or metal coupling pole may be detachably and adjustably clamped to th chassis of a logging trailer.

A further object of the invention is to provide a novel means for swivelly connecting the forward end of the coupling pole to a draft vehicle to provide for freedom of movement of the trailer relative to the draft vehicle to compensate for irregularity in the surfaces over which the vehicles are passing.

Other objects and advantages of the invention will hereinafter become more fully apparent from the following description of the drawings, which illustrate th preferred embodiments thereof, and wherein:

Figur 1 is a top plan view showing a log trailer, constructed in accordance with the invention. coupled to a draft vehicle;

Figure 2 is a side elevational view thereof;

Figure 3 is a transverse sectional view taken substantially along a plane as indicated by the line 33 of Figure 1;

Figure 4 is an enlarged transverse sectional view taken along the line 4-4 of Figure 1;

Figure 5 is an enlarged longitudinal view taken along the lin 5-5 of Figure 1;

Figure 6 is a plan view of one of the clamping inserts;

Figure '7 is a fragmentary horizontal sectional view showing the frame modified to receive a wood coupling pole;

Figure Bis a longitudinal vertical sectional view taken substantially along the plane of the line B8 of Figure 7; and

Figure 9 is a view similar to Figure 4 but showing the clamp engaging the wood coupling pole,

Referring more particularly to the drawings, Wllffl'Clll lik reference characters designate like or corresponding parts throughout the several views. l0 designates generally the improved logging trailer in its entirety and which includes 1i chassis frame, designated generally I I, The chassis frame ll includes corresponding side members l2 and the corresponding front and rear or end members l3. As best seen in Figure 3, the side members I2 are each formed of a channel memher and the end members l3 are each formed of two channel beams M which are connected by fastenings l5 to the flanges of the channel members l2, The upper channel members l4 open upwardly and the lower channel members l4 open downwardly, as clearly illustrated in Figure 2.

A pair of spring brackets l6 are secured to and depend from each of the side members l2 and are detachably connected at their lower ends by fastenings IT to the ends of leaf springs IS, The intermediate portions of the leaf springs l8 rest on an axle l9 and are secured thereto by fastenings 20. A pair of wheels, equipped with ground engaging pneumatic tires, is mounted on each end of the axle l9. Said wheels H, are located outwardly of the side of the frame II, as seen in Figure 3,

An H-beam 22 is supported on chassis frame ll and is disposed transversely thereof. Beam 22 is secured to the side members l2 by bracket 23 and fastenings 24. The coupling pole engaging means, as best illustrated in Figures 4 and 5, and which is identical at both front and rear ends of th chassis frame ll, includes the lower channel beams I6 which are provided with spaced upstanding walls 25 which are transversely disposed relatively thereto and which are secured to the webs of th lower channel members It in any suitable manner as by welding at 26 A block 21 of any suitable material is clamped between the complementary plates 25 to form a support, as will hereinafter become apparent The upper channel members M are provided with angle members 28 having complementary sides secured to the undcrsidcs of the webs thereof as by welding at 29. The depending sides or flanges of the members 28 are spaced the same distance apart as plates 25. As best seen in Figure 4, a bar 30 is secured by a rivet 3i within each of the channel members l4. Bars 30 are each provided with upslimling sleeves 32 at thrends thereof the alum with openings 33 and 35 in lune ill llllll "he .wu: of the upper ('llIlIlfl :l members l4 and mi lun'izcontnl flanges o he smile members 28, rw nl ilirul r. Clamping hulls 3S pro wit upwardly llll'l il!ll openings 35 in th lmrer channel turmbrrs 4 and each pass through an opening 33,

an opmilng 3d and the bore of a sleeve 32. The

upper ends of the clamping bolts are threaded to receive nuts 31 which bear against the upper ends of the sleeves 32. In Figures 1 to 6, the trailer ll] is shown in conjunction with a metal coupling pole 38 which is circular in cross section. as best seen in Figure 4. When the clamp ing means. is shown in Figures 4 and 5, are employed in conjunction with a pole 38 inserts or adapters 39 are utilized. The adapters 39. as best seen in Figure 6, each comprise a channel member to the ends of which are connected plate 4| in any suitable manner as by welding at 42. The outer edges of the plates 4| are provided with urcuat shaped recesses 43 for receiving the coupling pole 38, as clearly illustrated in Figures 4 .ind 5. The opposite edges of the plates 4| project beyond the base or webs of the members 40 to form retaining flanges 44. One of the ddzipters 39 is disposed on the block 21 be.- lween the plates 25 with its flanges 44 abutting against the, ends of the block 2?. as best seen in Figure 5 Similarly. an adapter 39 is disposed betwe n the complementary angle members 28 wi h its flzinces d4 engaging the sides of the upper channel member [4. It will be readily apparent that the coupling pole 38 retains the adapters 39 in applied position. as seen in Figures 4 (ind 5. The beams l4 ar sufficiently resilient so that the nut 31 can be tightened for clamping th coin pling pole 38 between the pairs of adapters 39.

Referring to Figures 1 and 3, a part f h Wil' end of a. draft vehicle is shown at and includes a plate or disc 45 to which on H-besim 4? is suitably secured. intermediate of its ends The disc 46 is provided with spaced upstanding pl'ites 48 having openings through which a pin e; 1 49 extends and in which the pin or bolt 49 is removabl v disposed. As best seen in Figure. 2 the coupling pole 38 is provided, adjacent in: for ward end. with an upwardly inclined portion to offset the forward end of the pole 38 upwardly relatively to the rear end thereof The threaded bolt or shank 50 projects from the forward end of the pole 38 to rotatably receive the sleeve 5| which forms the shank of a swivel 52v The nut 53 engages the outer end of the bolt 50 to retain the swivel 52 in position on the bolt 50 The swivel 52 includes a yoke 54 which extend from the sleeve 5| and has collar portions 55 at the ends thereof which rotatably engage the pin 49 for pivotally connecting the wivel thereto. It will thus be seen that the swivel 52 is pivoted to draft vehicle 45 and swivell connected to the pole 38 to form a universal connection between the draft vehicle and trailer.

As seen in Figure 2. the H-beams 22 and RT are disposed at substantially the same level and form the supporting surface for the load to be hauled which mav be logs. poles. etc The nds of the H-beiims 22 and 41 are provid d with mills or loops 5G or 5'! to be encased b llffffilill' metins, no shown, such as cha ns for sec iiinc the loud on Th H-betims 22 and 41.

An H-bezim 59 has one end thereof l'lhilllt: on the forward end of the pole 58 and fasten d thereto by bolts 60 which extend through the ((91) of th beam 59 and through the pole 58 and which are p dried with nuts 6|. A bolt B2. intended for the same i .irpose as the bolt 5:] projects from the forward rod of the beam 59 and is fastened llzrrelo by a loop 53 and a ring 54, or in :inv ot s-uituhi manner desired.
